<title>Fast switching and gain control of optical repeater units for burst mode upstream transmission over super-PONs</title>

Abstract

This paper presents a fast switching and gain control technique of optical repeater units (ORUs) for burst mode upstream transmission over a Super-PON system by using semiconductor optical amplifiers (SOAs). Measurement results confirm that switching of the SOA can be accomplished within 3 bits at 155.52 Mbps and that the gain control range is more than 10 dB. Downstream communication is in single talker and continuous mode, therefore no fast gain setting is needed. This allows us to use low noise figure (NF) Erbium Doped Fiber Amplifiers (EDFAs) with high O-8194-2294-O/96/$6.OO SPIE Vol. 2893 / 19 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/24/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx

<title>Performance of burst-mode receiver and optical repeater units in SuperPON</title>

“…In this paper some results of the research in the ACTS project PLANET [1][2][3][4][5], which aims at the realisation of an optical super access network (SuperPON), are presented. The paper will focus on the realisation of a Time Domain Multiple Access (TDMA) uplink at 3 1 lMbitls.…”
